4. Install a Conext System Control Panel or Conext ComBox to configure
programmable settings and to name specific network components, as
needed. See “Conext XW+ Inverter/Charger Accessories Installation” on
page 5–1.
Up to three Conext XW+ units can be connected to a PDP in a split-phase
system. To connect two Conext XW+ units to a PDP, see “Dual Inverter/Charger
Installation” on page 3–38. To connect three Conext XW+ Inverter/Chargers to a
PDP, see “Triple Inverter/Charger Installation” on page 3–44.
Conext XW+ Inverter/Charger Grounding
The Conext XW+ is provided with ground terminals that must be reliably
connected to ground (protective earth) by appropriately sized equipment
grounding conductors. System grounding for the AC and DC systems must be
done according to all applicable NEC and local installation codes.
For more information about system grounding, see “Grounding the DC System”
on page 3–8 and “AC Equipment Grounding” on page 3–20.
Dual Inverter/Charger Installation
This section provides instructions for adding a second Conext XW+ to your
installation. Complete the following installation steps only after you have already
connected the PDP to the first Conext XW+, as shown in “Wiring the Conext XW+
Inverter/Charger with a PDP” on page 3–7.
DC Grounding
See “Grounding the DC System” on page 3–8.
Note: When installing more than one Conext XW+ Inverter/Charger at a location,
use a Conext System Control Panel, Conext ComBox, or Conext Configuration
Tool to give a unique name to each Conext XW+ (and other Xanbus-enabled
devices), and to modify the factory-installed default settings to match and
support the installed configuration.
WARNING
UNGROUNDED EQUIPMENT
Equipment ground terminals must be reliably connected to ground by
appropriately sized grounding conductors. All installations must comply with
national and local codes. Consult local and national codes for specific
grounding and bonding requirements.
Failure to follow these instructions can result in death or serious injury.
